Comparison of the Magnetocardiographic Localization Accuracy Using Simultaneous and Sequential Recordings in a Single and Multiple Planes
Thorough phantom and patient studies conducted during Stimulation at a known site using a biomagnetic multichannel system (37 SQUID system Kremkon®) have demonstrated a localization accuracy of about 15 mm for recordings in a single plane. . With a growing distance from the source to the sensors, an increasing spatial error, mainly concerning the depth of the localization result was observed, which could impair especially cardiac investigations . In the course of technical progress, multiplane systems (e.g., 2×37 Channels) have become available for cardiac applications. In the MagnesII® system (BTI, San Diego), the second set of sensors can be approached to the patient’s back ftom a dorsal position.
